WTF?
My work with Democrats started in high school, when I was an alternate-delegate for Hillary Clinton.
Then you just weren't paying attention, because that was the peak of Democratic smug elitism. That was the period when it was just about impossible to read anything by or about any Democrats without seeing them making scoffing, condescending references to "flyover country " and "Jesusland." The Democrats of the early 2000s weren't just elitist, but overt about it - they didn't just think they were better than everyone else (and particularly everyone outside of New England and Cascadia) - they told us so, on a virtually daily basis.
Either you're shamefully ignorant or a fraud, because without a doubt the current Democrats are less - not more, but less - elitist than they've been at least since Bill Clinton.
